Key Battlegrounds: Utah, Maryland Redistricting vs. South Carolina GOP Runoff Dominate Democratic Primaries

Redistricting will reshape Democratic primary contests in Utah and Maryland on Tuesday, while South Carolina’s Republican runoff election hinges on a contentious redistricting dispute that could delay final results. The races come as U.S. states grapple with legal challenges and political maneuvering over new electoral maps drawn after the 2020 Census, with implications for the 2026 midterm elections and beyond.

In Utah, Democrats are competing in a primary for a single congressional seat in a newly drawn district that consolidates parts of Salt Lake County and Utah County, according to the Utah Legislature’s redistricting plan. The state’s Democratic Party has warned that the map, approved by a Republican-led legislature, could dilute Democratic voting power by spreading their supporters across multiple districts. “This is a clear attempt to lock in Republican control for the next decade,” said Utah Democratic Party Chair Dana Johnson in a statement last week.

Maryland’s primary features a high-stakes race in the newly redrawn 6th Congressional District, where Democrats are vying to replace retiring incumbent Rep. David Trone (D-MD). The district, which now includes parts of Anne Arundel and Howard counties, has been criticized by some Democratic lawmakers as overly favorable to Republicans due to its shape. The Maryland State Board of Elections confirmed that early voting began June 17, with Election Day on June 24.

Meanwhile, South Carolina’s Republican primary runoff for the state’s 1st Congressional District remains unresolved after a federal court ordered a redraw of the district due to a violation of the Voting Rights Act. The state’s Republican Party had drawn a map that packed Black voters into a single district, reducing their influence in neighboring districts. A three-judge panel ruled in February that the map must be redrawn, but the state legislature has yet to finalize a new plan. As a result, the runoff between Rep. Nancy Mace and Katie Arrington could face delays, with some legal experts suggesting results may not be certified until July.

Why redistricting matters

Redistricting—redrawing electoral boundaries after each Census—is a routine but politically explosive process in the U.S. The current cycle has been marked by unprecedented legal battles, with courts in multiple states striking down maps as unconstitutional. In Utah, the new congressional map reduced the number of competitive districts, a trend observed in states like Texas and Florida, where Republican-led legislatures have drawn maps to secure long-term GOP advantages. According to the Brennan Center for Justice, nearly half of all U.S. House districts are now considered “safe” for one party or the other, up from 30% in 2012.

The stakes are particularly high in Maryland, where Democrats have held a narrow majority in the U.S. House delegation. The 6th District’s new boundaries have drawn criticism from Democratic strategists, who argue that the map’s shape—stretching from suburban Baltimore to rural areas—could favor Republican candidates in future elections. “This isn’t just about one race; it’s about the future of Maryland’s representation in Congress,” said Del. Dereck Davis (D-Baltimore), a member of the state legislative delegation.

How the disputes could affect 2026

The delays in South Carolina underscore the broader impact of redistricting on election timelines. With the runoff results potentially delayed, the state’s Republican Party faces pressure to finalize a new congressional map before the 2026 midterms. Legal experts warn that prolonged disputes could lead to last-minute court interventions, similar to what occurred in North Carolina in 2022, where a federal court redrew maps just weeks before the election.

In Utah, the Democratic Party has filed a lawsuit challenging the state’s new congressional map, arguing it violates the Voting Rights Act by diluting minority voting strength. The case is pending before the U.S. District Court for the District of Utah, with a ruling expected by late summer. If the court sides with Democrats, the state could be forced to redraw the map before the 2026 elections, further complicating the political landscape.

For voters, the primary races in these states offer a glimpse into how redistricting is reshaping American politics. In Maryland, the 6th District race is a test of whether Democrats can retain control in a newly configured district. In Utah, the outcome could signal whether the state’s growing urban areas will gain more political influence. And in South Carolina, the unresolved runoff highlights the risks of partisan gerrymandering—a practice that has drawn scrutiny from both major parties in recent years.

What happens next

Results from Tuesday’s primaries in Utah and Maryland are expected by late evening, though some races—particularly in Maryland’s 6th District—may require recounts due to the close margins predicted by polls. In South Carolina, the runoff’s outcome remains uncertain, with legal challenges likely to extend into July. The state’s Republican leaders have signaled they will expedite the redistricting process to avoid further delays, but no new map has been proposed as of June 23.

Beyond the immediate races, the redistricting battles in these states will set the stage for the 2026 midterms. With control of the U.S. House hanging in the balance, both parties are closely watching how these maps perform in practice. “The next two years will be critical in determining whether gerrymandering continues to dominate our elections or if courts and voters push back,” said David Daley, a senior fellow at the FairVote organization, which tracks electoral fairness.

For now, voters in Utah, Maryland, and South Carolina will decide Tuesday’s races under maps that have already sparked controversy. The outcomes could foreshadow a broader trend: whether the 2020 Census-driven redistricting will further entrench partisan control—or whether legal challenges and voter activism will force a shift toward more competitive districts.
